How to see data returned in RC2? (4283023)

In SqlPlus, when querying 1st and 2nd RC using...

exec packag.proc(param1,param2,:rc1,:rc2);
print rc1
print rc2

Whilst the contents of RC1appears in Toad, how is it possible to see the data returned in RC2?

See below for example:

see sql statement:and see pacakge

CITDEV1(ABC)> @toad_test.pks
Package created.
CITDEV1(ABC)> @toad_test.pkb

Package body created.

The test can be re-created in SqlPlus as...

CITDEV1(ABC)> variable rc1 refcursor
CITDEV1(ABC)> variable rc2 refcursor
CITDEV1(ABC)> exec toad_test.get_data(:rc1,:rc2);
PL/SQL procedure successfully completed.

CITDEV1(ABC)> print rc1
